OET10100019 - Oetiker 1315 Double Ear Clamp 13-15mm Zinc Plated

Precision Engineering for Secure Fluid Lines

The Oetiker 2-Ear Zinc-Plated Hose Clamp (Model 1315 / Part 10100019) represents the industry standard for permanent, tamper-proof hose connections. Designed for applications requiring high sealing reliability, this clamp features a clamping range of 0.492 inches to 0.591 inches (approximately 12.5mm to 15mm), making it ideal for a variety of industrial, automotive, and MRO applications. Unlike screw-type clamps that can loosen over time due to vibration, the Oetiker ear clamp is permanently deformed during installation, creating a constant, spring-like tension on the hose.

Constructed from high-quality zinc-plated steel, this clamp offers a balance of strength and corrosion resistance suitable for most indoor and protected outdoor environments. The defining feature of the 2-ear design is its extended elasticity. In applications where the hose is subject to thermal cycling—such as welding water cooler lines or pneumatic systems—the hose material expands and contracts. The two ears act as springs, accommodating these changes in size without losing the seal or damaging the hose material. This "breathing" capability significantly extends the life of the connection and prevents leaks that can occur with rigid clamping methods.

Installation is achieved using standard Oetiker pincers, which crimp the ears to the required tension. The visible deformation of the ears serves as an immediate visual quality control check, ensuring the clamp has been properly closed. Furthermore, the band edges are carefully deburred to prevent the metal from cutting into the hose rubber during crimping, preserving the structural integrity of the fluid line. For maintenance and repair operations requiring absolute reliability, the Oetiker 1315 is the superior choice.
